Still another object is to simplify and cheapen the construction of parts while maintaining all the advantages of more compleX structures.

'Withthese objects in view the invention comprises various features of construction as hereinafter setqforth. f

The length of these sleeves G-"is, howevenlimited so as to p'errnit of the insertionltof the same fromthe space D within the yoke C. H and H" are bevel pinions mternieshing with the bevel gear wheels F and F, andialso arranged in the soace D within the yoke C.

The washers K and I espacing block L are then placed in position of axial alinement, after which vthe in J is inserted'through the alined mem 'ers, and the yoke being finally locked by the insertion of the "cross pin or cotper M.- This will-complete the assembly, and t will be noted thatthe gear wheels and pinions "proper relative position, while longitudinalmovement either direction.

WhaflIf claim as my. invention is: -1. a 'jdifferential gearing, the combination with a yoke frame having alined hubs ato'pposite ends thereof, gear wheels journaled in said hubs insertible therein from within the yoke, a pinion intermeshing with said ear wheels within the yoke, a shaft exten ing across said yoke upon which the ;,,-:;'pinion is journaled, and a block sleeved upon the" shaft and directly engaging the gear I wheels, said block forming a spacer between e gear wheels and a direct bearing therefor. 2.
